RAKING ATTACHMENT FOR HARvEsTER-BINDRS.

SPECIFICATION formingV part of Letters Patent No. 263,699, dated September 5, 1882. Application mod July 13,1882. (No modelli To all whom it may concern:

Be it known that I, J osIAH D. HEEBNER,

of Lansdale, in the county of Montgomery and Stale of Pennsylvania, have invented certain new and useful Improvements in Itaking Mechanism for Harvester-Binders and I do hereby declare the following to be afull, clear,and exact description of the same, reference being hadto the accompanying drawings, forming part of this specification, in which- Figure 1 is a top plan view of my invention. Fig.2 isatransverse section of the same,taken on the line y y, Fig. l. Fig. 3 is a sectional view, showing a portion of the endless traveling platform and one of'the sprocketwheels by which the sameis given motion. Fig. 4 is an enlarged top plan view of a section of the platform. Fig.l 5 is a view of a portion of one of the bars composing the platform detached. Fig. 6 shows the means for connecting the platform bars or slats together. Fig. 7 is a detail sectional view taken on the line so w, Fig. 4. Fig. 8 is a perspective view of one of y the sprocket-wheels detached. Figs. 9 and 9a are sectional views, showingtthe means for tightening the endless platform. Figs. 10,11, 12, and 13 are views illustrating different modiications ofthe means for uniting the bars composing the platform. Fig. 14 shows a means for strengthening the traveling platform at the middle.

Similar letters of reference in the several figures denote the same parts.

My invention relates to that Vclass of harvester-binders in which the out grain falls upon an `endless grain-platform and is carried by the latter direct to the binding mechanism to be bound, or else to an elevator, to be bythat in turn conveyed to the binding mechanism; and it consists in certain novel improvements in construction and combinations of parts, which I will first describe at length, and then point out particularly in the claims at the end of this specification.

Referring to the drawings, A represents the main frame of the grain-platform, constructed of the general forni shown, and having at its front edge the usual finger-bar, with its lingers b, and the cutte'rbar or knife-bar B, adapted to play back and forth in said linger-bar, as shown.

G' is the inner guard or shoe, b b2 the outer shoe, and b3 the grain-wheel for supporting the platform at the outer end.

Mounted in .suitable bearings at opposite ends of the platform are two transverse shafts, E E2, each carrying two sprocket-wheels, E, one at the front and the other at the rear ot' the platform. These sprocket-wheels are preferably polygonally-shaped, and are provided with conical projections or studs e, located centrally, one on each face, as shown in Figs. 3 and 8. Passing around these sprocket-wheels is an endless apron or carrier, D, which, for convenience', I shall term an endless platform.7 This endless platform is composed of transverse bars or slats d, preferably of the form in cross-section of a frustum of a pyra- V mid, asshown in Fig, and united preferably by means of staples F and links F', as shownv in Figs. 5 'and 6, the bases of the bars or slats forming a close joint, as shown in Fig. 3, and the staples being driven into the end of each bar, so as to secure the opposite ends of two links, as shown in Figs. 3 and 4. Metal cappieces K are preferably slipped upon the ends of the bars and the staples driven through to secure them, as shown in Fig. 5. .llhe bars d are each provided with a conical recess or cavity, d', as shown in Figs.3, 4, and 5, with which the correspondingly shaped projections or studs@ on the sprocket-wheel engage when the endless platform is in motion.

For the purpose of supporting the endless platform throughout its entire extent and preventing it from sagging under its own weight and that of the grain upon it, I provide an elevated track, consisting preferably of metal bars c c, arranged underneath the lateral edges of the endless platform and resting upon timbers C C', located respectively at the front and rear of the platform-frame, as shown in Figs. l and 2.

To prevent lateral movement of the endless platform whilein motion, Iprovide every third, fourth, or ftli `bar d with inwardly-projecting pins d2, Figs. 2, 4, 5, and 7, and form longitudinal channels or grooves C2 in the timbers C C', as shown in Figs. 4 and 7, for accommodating and guiding said pins. The pins, by bearing against the walls of the channels, cause a steadiness and evenness of movement ofthe platform.

The peculiar form of the slats or bars composing the endless platform causes V-shaped spaces to be left between them, into which the cut grain falls and is conveyed away with positiveness, whilelthe bases of said bars or slats are so close together as to prevent any grain from falling through and clogging the action of the mechanism.

As the endless platform passes around the polygonally-faced sprocket-wheels at the delivery end, the proximate sides of the bars, instead of forming au acute angle, as in the greater part of their course, form a very obtuse angle, as shown in Fig. 3, thereby rendering the ejection of' the grain easier, and also preventing any grain from being carried around and under, as will be readily understood.

While I prefer to use the links and staples shown in Fig. 6 as the means for fastening the bars of the platform together, yet I may use any equivalent thereof-such, for instance, as a continuous flexible strap, d5, threaded through the bars, as shown in Fig. 1l, or a plain flexible strap, d6, secured to the bottoms of the bars by staples or other equivalent fastenings, as shown in Figs. l2 and .1.3.

When necessary or desirable the endless platform may be further strengthened by the application of an additional series of links, F3, and staples F2, located at or near the middle, as shown in Figs. 2 and 14 one staple serving in this instance also to secure the opposite ends of two links.

The transverse sprocket-wheel shaft E has secured to its forward extremity an additional sprocket-wheel,which is driven by means of an endless chain, G, geared to the main drivewheel of the machine. (Not shown.) The movement of the endless platform is in the direction indicated by the arrow.

I preferably mount the outer` transverse sprocket-wheel shaft, E2, in bearing-blocks E3, rendered adjustable back and forth fin guides E4 by means of the screw-bolts E5 and nuts E, as shown in Figs. 9 and 9u. By this provision the tension of the endless platform can be regulated at pleasure by simply tightening or loosening the nuts E6.

While I have described my improved form of endless raking-platform as applied to harvester-binders, it is evident that it may be applied to the grain-platforms of ordinary harvesters and elsewhere where applicable.

Having thus described my invention, I claim as new- 1. The endless platform, constructed of bars or slats of pyramidal'shape in cross-section and forming close joints with each other at their bases, and means for articulating said bars together, substantially as described.

2. In the herein-described endlessplatform,

the combination, with the transverse bars or slats pyramidal shaped in cross-section, of the connecting-links and the staples driven in the ends of the bars, and each operating to secure the opposite ends of two links, substantially as described.

3. .The combination, with the endless platform and the sprocket-wheels, constructed as described, of the elevated trackway, the longitudinal guiding-grooves O2 in the supports C C of the trackway, and the pins d2, secured to the bars of the endless platform and working in said longitudinal grooves, substantially as described.
